Additional Manufacturer Narrative
Combination product: yes.Neither the affected device not the angiographic material was returned.Therefore, no technical investigation on the subject could be performed.The production documentation was reviewed to establish whether a deviation from the manufacturing process could be the cause for the reported event.Review of the production documentation confirmed that the device was manufactured according to specifications and passed all in-process and final inspections.During final inspection, every stent system undergoes visual inspection to ensure correct stent embedding and homogeneous crimping of the stent.Further, the stent retention force of a defined amount of samples is tested by means of manufacturing process output monitoring.Based on the conducted investigations, no material or manufacturing related root cause could be identified.Consid-ering the event description, the most probable root cause for the reported event is related to the patient's anatomy (i.E.Previously implanted stent).
Event or Problem Description
The orsiro mission drug-eluting stent system was selected for treatment of a calcified lesion in a tortuous segment of the bifurcation lcx/om1 where a previously implanted stent was present.Pre-dilation was performed using a 2.0/12 mini trek balloon.The affected device was introduced into the patient's body and advanced towards the target lesion, but got caught at the previously implanted stent.As a result, the stent was stripped off the balloon.The physician was able to secure the stent to the vessel wall at the site where it had become dislodged using a 2.5/10 medtronic euphora balloon.There was no harm to the patient.
